2.1 Measuring principle
Fig. 1 THERMOR measuring cuvette (schematic)
Sample gas flows around the measuring resistors in the THERMOR measuring cuvette. The
cooling effect of the sample gas on the measuring resistors is measured. The higher the
thermal conductivity of the sample gas, the more the measuring resistor is cooled.
This measuring principle is basically suitable for gas mixtures consisting of two individual
gas components whose specific thermal conductivity differs considerably (binary gas mix-
tures). The higher the concentration of the gas component with high specific thermal con-
ductivity, the stronger the measuring effect. This results directly in the concentration of this
gas component. The measuring principle serves usually for measuring gases with a partic-
ularly high specific thermal conductivity.
2.2 Application area
The Analyzer module THERMOR can measure the concentration of Ar, CH

, CO

, H

, He,

and other gases in binary or quasi-binary gas mixtures.
Non-binary gas mixtures can be measured when the influence of interfering gas compo-
nents is automatically compensated (cross-sensitivity compensation). For this purpose, the
concentration of these gas components must be measured with different Analyzer mod-
ules or different gas analyzers. The parameters for cross-sensitivity compensation are set
individually for each case (option).

3.3.3 Damping
Constant damping
When "damping" has been programmed, the average value from the current measured
value and the previous measured values (floating averaging) are displayed instead of the
current measured value.
Possible uses include:
Damping metrological measured value fluctuations (noise)
Smoothing fluctuating measured values when only the average value is relevant
Damping is done in the Analyzer module and therefore affects all measured value displays
and outputs. It is also active during an adjustment procedure.
Dynamic damping
“Dynamic damping” serves to compensate measured value fluctuations without signifi-
cantly increasing the reaction time. Dynamic damping is automatically deactivated when
the measured value changes rapidly and strongly as against “normal” damping. This allows
“smoothing” continuous minor measured value fluctuations but rapid measured value
changes are still displayed without delay. Dynamic behavior is determined with the
“Threshold” parameter:
When the measured values change only slowly, dynamic damping functions as constant
damping.
When the difference of successive measured values is greater than the set limit,
dynamic damping is terminated automatically and remains disabled as long as the
measured values continue to change rapidly.
Dynamic damping is active again when measured value differences are below the limit
again (which means measured values changes remain slight).
Dynamic damping also affects all measured value displays and outputs.
Increasing damping normally increases the reaction time (90% time) of the
gas analysis system accordingly.
Reducing damping can possibly increase the measurement signal “noise”
(measuring turbulence).
Time constant = 0 s means: No damping.
CAUTION: Risk of incorrect adjustment
The “Measuring time, test gas” must be at least 150% of the set damping time
constant during adjustments.
When damping has been reset or increased: Check whether adjustment
settings need to be adapted.

3.3.4 Drift limit values
Purpose
Analyzer module drifts are caused, for example, by contamination, mechanical changes or
aging effects. The total drift (i.e. the deviation from original state) increases gradually. It is
not practical to keep compensating an ever increasing total drift through computation.
Inspect and reset the Analyzer module when total drift has become very large.
Drift limit values monitor total drift automatically. These also protect against erroneous
adjustments.
Functionality
After every adjustment, an Analyzer module compares the calculated total drift with the
drift limit value. Drift limit value violation is reported in two stages:
Status “M” (Maintenance request) is activated when the total drift reaches 100 … 120%
of the drift limit value.
Status “F” (Failure) is activated when the total drift reaches more than 120% of the drift
limit value.
When an adjustment procedure shows that a calculated drift has reached more than
150% of the drift limit value, the result from this adjustment procedure is ignored and
the previous adjustment remains valid.
3.3.5 Deleting adjustment results
The “Delete results” function deletes all determined drift values of a measuring compo-
nent. Drift limit values then refer to new drift values.
The data of the previous adjustment which was performed before are then no longer dis-
played. Test gas settings (e. g. nominal value) are not changed.
The drift limit values are set in the factory (standard value: 10%).
A Service function is available to reset all drift values to “0” (Drift reset).
This is useful after Analyzer module maintenance when this has estab-
lished a new original state.
CAUTION: Risk of incorrect adjustment
If very large drift values are displayed after a manual adjustment procedure
( Operating Instructions “Basic Control Unit (BCU)”), a test gas used probably
did not match the relevant test gas setting or gas feed was interrupted – and
the adjustment result was still accepted.
Do not delete incorrect adjustment results, but repeat the adjustment care-
fully.
Do not use the deletion of adjustment results to nullify large drift values
caused by extensive physical changes of an Analyzer module. Instead,
clean the Analyzer module or perform an adjustment.
[1]
After an Analyzer module has been cleaned, altered or exchanged:
Delete the relevant adjustment results and perform an adjustment.

4.2 Test gases for the Analyzer module THERMOR
Composition of the test gases for the Analyzer module THERMOR
Test gases for measurements with physical reference value
For measuring ranges with the end value “100% by volume” or close to 100% by volume
(example: 80 100% by volume), the physical zero point can be100% by volume; i.e.
metrologically, the measuring range starts at 100% by volume and reaches from there to
the start value of the measuring range. This means, the measuring range function is
inverted.
In such cases:
Select the zero gas so that the nominal value is equivalent to the end value of the
measuring range.
Select the span gas so that the nominal value is at the start of the measuring range (in
the range of 0 … 35% of the measurement span).
Basic information on the test gases Operating Instructions “Series GMS800”
Test gas Composition (recommended) Nominal value (recommended)
Zero gas: Gas or gas mixture which represents
the sample gas at the start value of the
measuring range as exactly as possible

.
Span gas: Gas or gas mixture which represents
the sample gas at the end value of the
measuring range as exactly as possible

[1]
This can also be valid for measuring ranges with “suppressed zero point”
(example: 80 … 90% by volume).
In special versions, the physical reference value can also be a certain con-
centration of the measuring component.
Pay primary attention to the provided information on the test gases.
